39.99 + 0.15x <span>≤ 45
0.15x </span><span>≤ 5.01
x </span><span>≤ 33

the maximum </span>text message you send or receive is 33

39.99 + 0.15(33) = 44.94

Help with this math question

Ulleksa [173]

Answer:

$-\frac{13\sqrt{x} }{x}$

Step-by-step explanation:

We have been given the following expression;

-13/√x

In order to rationalize the denominator, we multiply the numerator and the denominator by √x;

$-\frac{13}{\sqrt{x}}=-\frac{13\sqrt{x} }{\sqrt{x}\sqrt{x}}\\ \\-\frac{13\sqrt{x} }{\sqrt{x^{2} } }\\\\-\frac{13\sqrt{x} }{x}$

A line of best fit predicts that when x equals 28, y will equal 27.255, but y actually equals 26. What is the residual in this c

zlopas [31]

Answer:

C) -1.255

Step-by-step explanation:

We are tasked to solve for the residual value given that when x equals 29, y will be equals to 27.255. But, when it is tested, y actual value is 26. The formula in solving residual is shown below:

Residual value = Observed value - predicted value

Residual value = 26 - 27.255

Residual values = -1.255

The answer is -1.255 for residual value.

Which of the following best describes the pattern in the diagram shown

Vikentia [17]

As you move from left to right, the number of points in the star increases by 1 and is the best option which describes the diagram which is therefore denoted as option B.

<h3>What is a Point?</h3>

This can be referred to an important object in geometry and is usually represented by a dot. It also helps to tell the exact location of substances or objects and doesn't have certain parameters such as the length or width.

We can deduce that Star 1 has four points, star 2 has five points and star 3 has six points. We can therefore infer that the stars in the diagram given below has some amount of points which increases by one as we move from left to right thereby making it the most appropriate choice in this type of scenario.

Sam receives 4 dollars more than Nathan for allowance. Nathan receives 8 dollars less than Hector. If Sam receives 15 dollars fo

QveST [7]

S = N + 4
N = H - 8
S = 15

S = N + 4

Plug in 15 for 'S':

15 = N + 4

11 = N

N = H - 8

11 = H - 8

Add 8 to both sides:

19 = H

So Hector receives $19 for allowance.
